Endangered Species on the only known inhabited Planet

65 million years ago probably a 10 km big planetoid wiped out around
the half of all at that time living species on our planet, among them all
Dinosaurs, flying Saurs and water-living ones and a considerable number
of another species. Even longer ago, a really all-life threatening catastrophe
led to an extinction, which caused around 90 % (!) of all living species
to vanish. The reasons for this last event are not well understood, partially
due to the longer time back it happened, but there are a few more mass
extinctions in the history of Earth and even one, which takes place at
now, and this time we know without any doubt the reason for it.
The only question remains, how severe our aggressive, totally unscrupulous
behaviour against all other living species will be. Which of the past events
we will rival with or even surpass? Should any intelligent being in millions
of years in the future discover this nowadays ongoing mass extinction,
it will have to solve a difficult riddle: no major impacts, no giant vulcanism
on global scale, no significant long-term climatic change. What has happened?
One thing is for sure: higher evolved species cause seldom casualties on
themselves or even on other species, but as the example of Lemmings in
Scandinavia shows, this happens nonetheless. The worst example is the mankind,
which threatens the entire terrestrial biosphere and therefore also itself.

In detail we use several ways of destroying life on Earth: the most
global ones are the additional heating of the atmosphere by enriching certain
gases in our atmosphere, mainly due to carbon dioxide by burning fossil
forms of biological mass and destruction of carbon dioxide depleting units
like forests (not only rain forests, also boreal ones are reduced rapidly)
altogether with methane, which is due mainly to stock-farming (cattles!),
the depletion of Ozone in higher layers of the atmosphere increases the
energy of the incoming ultraviolet radiation of the Sun on Earths surface,
the depletion of biomass in the oceans by far to extensive fishing directly
threatens all animals in these, the usage of ground for farming purposes
and for buildings of all types reduces greatly the available areas for
natural living animals.

Other factors, more specific for certain species, are direct hunting
of them for a number of nearly exclusively totally inacceptable reasons
(whaling, shooting of birds of prey, killing of mammals to get fur and
so on), reducing of their nutrients directly or indirectly (compare fishing
above), local human made catastrophes like fuel leakages of any type (for
example pipelines especially in Russia are a big threat) and a number of
further reasons, one is, extensive enlighting of cities at night, which
disturbs the living cycles of animals in theses regions cause major negative
impacts on the biosphere or at least significant parts of it.

The heating of atmosphere alone is a great danger, because plants and
most animals can't cope with the - in evolutional terms - rapid shift of
climatic zones, which is connected with this tendency. Only a global effort
can limit the unavoidable damages to Earths biosphere anyway. And the only
global organization that in my view fulfills all minimum requests for that
difficult task is the WWF, which means World Wide Fund for nature (formerly
known as World Widelife Fund). To bundle these efforts, it would be fine,
if more people would join it. Now I present three main sites of it: the
international, US and German member organizations of it.

These sites enable all people in the world the access on the world
wide but also the special local projects of the selected regions. For a
number of important countries own homepages exist, the other countries
should use the international one or a homepage of a close neighbor for
getting the appropriate informations. For it's a global effort, the projects
and country groups are ever growing, the most important ones are very ambitious,
but absolute necessary, if we want the things get really better.
